Mastering Docker - Third Edition

Overview of this book

Docker has been a game-changer when it comes to how modern applications are deployed and created. It has now grown into a key driver of innovation beyond system administration, with an impact on the world of web development. But how can you make sure you're keeping up with the innovations it's driving, or be sure you're using it to its full potential? Mastering Docker shows you how; this book not only demonstrates how to use Docker more effectively, but also helps you rethink and reimagine what's possible with it. You will cover concepts such as building, managing, and storing images, along with best practices to make you confident, before delving more into Docker security. You'll find everything related to extending and integrating Docker in new and innovative ways. Docker Compose, Docker Swarm, and Kubernetes will help you take control of your containers in an efficient manner. By the end of the book, you will have a broad, yet detailed, sense of what's possible with Docker, and how seamlessly it fits in with a range of other platforms and tools.

In this chapter, we looked at how to use Docker Machine to create the Docker hosts locally on VirtualBox and reviewed the commands you can use to both interact with and manage your Docker Machine-launched Docker hosts.

We then looked at how to use Docker Machine to deploy Docker hosts to your cloud environments, namely DigitalOcean. Finally, we took a very quick look at how to launch a different container-optimized Linux operating system, which was CoreOS.

I am sure you will agree that using Docker Machine made running these tasks, which typically have very different approaches, a very consistent experience, and which, in the long run, will save a lot of time as well as explaining.

In the next chapter, we are going to move away from interacting with single Docker hosts to launching and running a Docker Swarm cluster.
